Im new to prom burning and i have made several chips so far. But im not sure on what bin file is the best to use and how do you know what bin is right for your car? I have read alot but i cannot find out which bin i should use. I have a 91 z28 speed density 730 ecm and i have been using the 8d ecu file with Tunerpro.

 

AUJP for you. Find a virgin one. IMO you should never start with anything but a stock bin that way you are not working from what may have been someone elses mistakes...

 

Another good start would be he S_AUJP, developed here at thirdgen....

2 version
* one with CCP and AIR
* one without

are available at moates fileman site.

 

Well i got a aujp bin but i dont see a vats flag to turn off the security system. I really need that option since my lock is going out. Also my car surges while idling down at about 1500 no matter what chip i burn. Is there a setting that i may have off. I have 25lb injectors, headers, no smog, msd, afpr. All i have changed is the injector setting from 19 to 25 and turned off the vats.
